摘要： A high-pressure discharge lamp includes an arc tube portion enclosing a luminous material in the tube; a side tube portion substantially made of quartz glass that extends from the arc tube portion; and an electrode rod whose first end is arranged in the arc tube portion and a part of which is provided in the side tube portion. The electrode rod is substantially made of tungsten. A region containing at least one of copper oxide and copper is present in at least a part of the portion of the side tube portion in which the part of the electrode rod is positioned.

摘要： In a high intensity discharge lamp, at least one of an arc bend amount and an apparent width of arc is controlled by a simple configuration at low cost. A high intensity discharge lamp system 110 has a high intensity discharge lamp 111 and an operating circuit 113 for driving the high intensity discharge lamp 111. In the high intensity discharge lamp 111, a rare gas and a filling material 136 containing a metal halide as a light generating substance are enclosed in the arc tube 121 provided with a pair of electrodes 122a and 122b. The lamp system is disposed such that the line connecting the electrodes 122a and 122b is horizontal, and by applying a magnetic field having a vertical magnetic flux thereto and by varying the frequency of alternating current for driving the high intensity discharge lamp 111, at least one of an arc bend amount and an apparent width of arc can be easily controlled.

摘要： A discharge lamp for an automobile headlight has a light color that lies in a region common to the following three regions: a region bounded by an ellipse with a color point (u, v)=(0.224, 0.331) as a center thereof, a major axis of 0.080, a minor axis of 0.024, and an angle from a u axis of 35 degrees in the CIE 1960 UCS diagram; a region bounded by an ellipse with a color point (u, v)=(0.220, 0.332) as a center thereof, a major axis of 0.060, a minor axis of 0.022, and an angle from a u axis of 15 degrees in the CIE 1960 UCS diagram; and a region bounded by an ellipse with a color point (u, v)=(0.235, 0.335) as a center thereof, a major axis of 0.060, a minor axis of 0.030, and an angle from a u axis of 30 degrees in the CIE 1960 UCS diagram. The light color lies in a range on a side of color temperature lower than an isotemperature line of a correlated color temperature of 3800K and higher than an isotemperature line of a correlated color temperature of 3400K in the CIE 1960 UCS diagram.
